(PhysOrg.com) -- A diet rich in fish fatty acids has no effect on cognitive functions such as memory and concentration in the elderly. Nor does it affect their level of wellbeing. This is the conclusion drawn by Dutch researcher Ondine van de Rest in the thesis for which she got her PhD from the Wageningen University on 18 December. http://www.physorg.com/news180723607.html Medicine & Health Tue, 22 Dec 2009 17:30:03 EST news180723607 A Duke University study of more than 3,000 orphaned and abandoned children in five Asian and African countries has found that children in institutional orphanages fare as well or better than those who live in the community. http://www.physorg.com/news180338577.html Other Sciences Fri, 18 Dec 2009 06:20:02 EST news180338577 Persons with higher levels of leptin, a protein hormone produced by fat cells and involved in the regulation of appetite, may have an associated reduced incidence of Alzheimer disease and dementia, according to a study in the December 16 issue of JAMA. http://www.physorg.com/news180125848.html Medicine & Health Tue, 15 Dec 2009 19:30:02 EST news180125848 Nerve cells transplanted into brain-damaged rats helped them to fully recover their ability to learn and remember, probably by promoting nurturing, protective growth factors, according to a new study. http://www.physorg.com/news179589260.html Medicine & Health Wed, 09 Dec 2009 14:50:11 EST news179589260 Any parent knows that sometimes maintaining your cool with misbehaving children is a challenge. We all have times when we get frustrated or angry and lash out at someone without thinking. A new study by psychologists at Virginia Tech and two other universities suggests that parents with poorer working memory skills are less likely to be able to control their emotions with their children. http://www.physorg.com/news179504540.html Medicine & Health Tue, 08 Dec 2009 14:50:01 EST news179504540 Patients, discharged from hospitals on ventilator support and with cognitive impairments, fare poorly four months later.

But a new study from researchers at Washington University School of Medicine in St. Louis questions those assumptions. In fact, the researchers were not able to detect any long-term cognitive declines attributable to surgery in a group of 575 patients they studied. http://www.physorg.com/news177846255.html Medicine & Health Thu, 19 Nov 2009 09:45:53 EST news177846255 At birth, children with Down syndrome aren't developmentally delayed. But as they age, these kids fall behind. Memory deficits inherent in Down syndrome hinder learning, making it hard for the brain to collect experiences needed for normal cognitive development. http://www.physorg.com/news177777639.html Medicine & Health Wed, 18 Nov 2009 14:41:41 EST news177777639 The first ever large-scale, longitudinal study of ketamine users has been published online today in the journal Addiction. With Ketamine (K, Special K) use increasing faster than any other drug in the UK (British Crime Survey, 2008) this research showing the consequences of repeated ketamine use provides valuable information for users and addiction professionals alike. http://www.physorg.com/news177598981.html Medicine & Health Mon, 16 Nov 2009 13:20:03 EST news177598981 Societal and technological changes have taken place at a dizzying pace over recent decades.

The study shows that multiple abnormal processes in the brain are often involved in cases of dementia, and that the drugs currently in development to treat individual brain pathologies may have a limited impact on the overall burden of dementia in the population. http://www.physorg.com/news177058872.html Medicine & Health Tue, 10 Nov 2009 07:50:02 EST news177058872 Individuals with weaker muscles appear to have a higher risk for Alzheimer's disease and declines in cognitive function over time, according to a report in the November issue of Archives of Neurology. http://www.physorg.com/news177017452.html Medicine & Health Mon, 09 Nov 2009 20:00:01 EST news177017452 Human embryonic stem cells could help people with learning and memory deficits after radiation treatment for brain tumors, suggests a new UC Irvine study. http://www.physorg.com/news177008376.html Medicine & Health Mon, 09 Nov 2009 17:10:05 EST news177008376 St. Jude Children's Research Hospital and the University of Florida Proton Therapy Institute have formed a collaboration to provide proton therapy for St. Jude patients.

The problem, according to his latest research, is that many older drivers don`t realize that danger is coming at them sideways, not from head-on as they assumed. http://www.physorg.com/news169834951.html Other Sciences Tue, 18 Aug 2009 17:40:02 EST news169834951 With a vast majority of the world speaking more than one language, it is no wonder that psychologists are interested in its effect on cognitive functioning.
